Specificationforming part of Letters Patent No. 35,620, dated J une l?, 1862.

rI he disengaged end of the coiled pipe D projects a trifle above the drawer C.

` J is the plunger of the churn,which is composed of two bars, e e, crossing each other at right angles and connected at their point of intersection with the lower end of the dasherrodK, thelatter passing, as usual, through the` center of the lid f of the churn. The upperend of the rod K is connected by a pivot, g,

\ with the lever G, as shown in Fig. 1.

The two bars e e of the dasher are perforated with holes 71., through which the rods i of valves j pass, thevalves,when down,`closing the orifices ofthe holes h, which areconsiderably larger 'in diameter than the rods z'. The lower end of each rod is provided with a weight, k, and these weights, when free to act, are compe-f` tent to keep the valves j closed or down over the holes h. l

In the under side of eachbareof the dasher there are made openings or cavities l, which may be of circular form. These openings or cavities are concentric with the holes 71 but are much larger in diameter. h rIhe holes h communicate with. the openings or cavities l, asclearly shown in Fig. 1.

The parts above described compose the whole of the invention, and the operation is as follows: The churn A is supplid with a requisite quantity of cream, and in case warm air. is to be incorporated with the cream the drawer C is filled with warm Water. rThe lever Gr is then operated, and the dasher J moved up and down,and the bellowsE Worked simultaneously. As the bellows E operates' `air is forced through the coiled pipe D into chamber B, and the air, in passing through the coiled pipe D, is warmed by the water in the drawer O. This warm air is forced under the operation of the bellowsup the pipe I into the upper part of the churn A above the crea-m. Each timethe dasher J ascends above the surface t of the cream the openings or cavities l fill, of course, with warm air, and said air is carried .down through the cream as the dasher descends, andwhen the weights k come in contact with the bottom a the dasher is allowed` to descend a trifle farther down, so as to open the valves j, (see Fig. 1,) and the warm airV escapes from the openings Z through the holes h and passes up through the cri-carri,`

, taken in ved churn rt to fully similar to to re pipe, D, is at one end itable way d by. a rod,

ch commuthe upper as indicated by the arrows l. Thus it will be seen that the Warm air will be thoroughly incorporated with the cream. In case it is desired to incorporate cold air with the cream, the drawer C is supplied with cold Water. The churn A may have a thermometer, L, inserted in it in order to indicate the temperature of the cream.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, isH i l. The combination of the air-cells Z and valves j with the dasher J and bottom a, as

herein shown and described.
